提出了一种适用于大跨度、大空间建筑的火灾安全分析方法——性能化抗火设计方法.首先通过火灾场景分析及模拟计算,确定构件的温度,再利用分析软件计算各不同温度下构件的应力,确定需要防火保护的构件.青岛北站主站房建筑结构体系复杂,超大空间的建筑布局,超出现有建筑防火设计的规定,现行规范方法难以满足抗火安全性与经济性要求.基于性能化方法对青岛北站主站房的抗火安全性进行了评估,并根据评估结果确定防火保护措施.
A fire safety analysis method-performance-based fire-resistance design method for large-span and large-space buildings is proposed.First, through the analysis of the fire scene and the simulation calculation, the temperature of the components is determined, and then the analysis software is used to calculate the temperature of the components Of the stress, to determine the need for fire protection components.Qingdao North Station main station building complex structural system, large space building layout, beyond the existing fire safety design requirements, the current standard method is difficult to meet the requirements of fire safety and economy. Based on the performance-based method, the fire safety of the main station building of Qingdao North Railway Station was evaluated, and the fire protection measures were determined according to the assessment results.
